Bill Wendling c3cee57f7d Generate compact unwind encoding from CFI directives. 
We used to generate the compact unwind encoding from the machine
instructions. However, this had the problem that if the user used `-save-temps'
or compiled their hand-written `.s' file (with CFI directives), we wouldn't
generate the compact unwind encoding.

Move the algorithm that generates the compact unwind encoding into the
MCAsmBackend. This way we can generate the encoding whether the code is from a
`.ll' or `.s' file.

Akira Hatanaka 3e6758541b [mips] Enhance command line option "-mno-ldc1-sdc1" to expand base+index double 
precision loads and stores as well as reg+imm double precision loads and stores.

but now it takes place during legalization. As a result, users will see double
precision stores and loads being emitted to spill and restore 64-bit FP registers.

Richard Smith 9401181aed Remove verifier check that attribute 'builtin' is only applied to calls to

regardless.

Manman Ren 0b3d39235a TBAA: add isTBAAVtableAccess to MDNode so clients can call the function 
instead of having its own implementation.

The implementation of isTBAAVtableAccess is in TypeBasedAliasAnalysis.cpp
since it is related to the format of TBAA metadata.

The path for struct-path tbaa will be exercised by
test/Instrumentation/ThreadSanitizer/read_from_global.ll, vptr_read.ll, and
vptr_update.ll when struct-path tbaa is on by default.
